1. A terminal comprising:
a receiver that receives multiple downlink control information (DCI) scheduling a first physical downlink shared channel (PDSCH) from a first transmission and reception point (TRP) and a second PDSCH from a second TRP; and
a processor that generates a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook which is common between the first TRP and the second TRP, based on a counter downlink assignment index (counter DAI) counted in order of indexes corresponding to the first TRP and the second TRP and a total DAI indicating a total number of PDSCHs from the first TRP and the second TRP, the counter DAI and the total DAI being included in the multiple DCI.
